Description

When following the steps - do not click on 'Apply Changes button'!

  1. In VE-> Categories. Add three categories
  2. Click on the drop-down arrow to delete two of them.
  3. Click 'Cancel'
  4. Re-open the box and one of the categories is still there
  5. Try to delete the remaining category - Uncaught TypeError is displayed:

Error: Cannot remove detached item
remove (undefined, line 380)
onRemoveCategory

onClick
(anonymous function) ([native code], line 0)
dispatch (load.php, line 65)

Or

After clicking the 'Apply button' at any step(even at the last one when it looks like a category cannot be removed), all come back to normal workflow and all categories get deleted.

I can't reproduce step 4 - I reopened the categories dialog, but the categories are still all gone.

Re-opening: the issue is present in beta, test2, and production - attached the screencast. The issue is not too serious- those 'detached' categories are not saved.

As Alex noticed - re-arranging the categories(dragging them) - and then deleting them causes errors when the Options-Categories dialog is re-opened.

The clarified steps:

  1. Add three categories - AA, BB, CC
  2. Move CC category - insert it in front of BB, then in front of AA (the sequence seems to be important)
  3. Delete AA and BB - click 'Cancel'
  4. Re-open Categories - CC category remains displayed.
  5. Click CC to delete -

Error: Cannot remove detached item
and sometime

TypeError: this.categories[name] is undefined
